A gas-receiving casing; 38 is provided with a; top which is securefithereto by means of screws 4:0. The casing is di vided into chambers i1,42, and "416, by means of the diaphragm ig'which is preferably securedin the annular depression in the cap 01- over 39 by solder, orUthGF-Wibfi, us a The diaphragm adapted to b sited; upon an annular rim01" valve seat, 'WIiiii; surrc-i the chamber 16. in: em 0m P11333101}sap i is swim! )hli glll 43 a, c: us

The casing 38 is secured to the jacket 10 as by screws 57, as a meansfor supporting the gas burner-29; and as a further means by screws 59.

' the opening for "supporting the burner part thereof, an arm 58 may besecured to the jacket 10, as an ignition burner 60 is located near onevof the openings in one of the arms 30 of the gas burner 29 and is con-.nected to the pipe 53, as by the small pipe 61, so asto supplfasmallconstantly burning flame for igniting the burner when the cock is turnedin the proper direction. A small pipe 62 i's connected to the center ofthe top or cap 390i the controlling device and cpmmunicates with thechamber 42 above the diaphragm. It terminates in a thin Walledreceptacle 64; adapted to be located near the vertical Wall of thevessell when the latter is in place. It is inclosed in a smallvertically extending flue, prpvided by the cap portion" 65, which freelyencompasses the receptacle ti l, the cap portion being securedpermanently to the outside vertical Wall of the vessel. let, The lowerend of the line 66 is open, and communication is established bet-weenthe upper end of the this 66 and the interior of the. vessel let bymeans of a plurality of perforations 67. The operation f the device issubstantially as follows: With the parts in the positions shown in Fig.2 and the vessel 1.4 containing food to be steamed or boiled, when thegas cook 55 is turned so as to admit gas into the burner 29, the gas isimmediatelyignited by the lighting burner 60. The spring d7 at this timeholds-the dia' phragm away from the seat a5. and permits gas to passfrom the pipe 53 through 5% into the chamber 46 and from the chamber 46into the chamber, 4.1. be-

tween the seat 45andthe bottom surface of v the diaphragm From thechamber 41 it passes through the pipe 5 into the'p'ipei 3'7 and thenceinto the burner, and gas will thus continue to pass into the burner -29so long as the diaphragm t3 is'unseated or raised above from theannular: seat 45 of the chamber When the pressure of the spring 132,however, isovercome and the diais-caused to be seated upon the annularseat 45 gas will be shut oil from the burner When the temperature beginsto rise in the vessel 14, a small quantity of hbt air or steam willbegin to leave the vessel 14' and pass through the orifices 6? down toflue 66, thus heating the air or other'fiuid within thereceptacle 64:,and thereby expanding the fluid contained in the said receptacle and thepipe 62 which communicates with the chamber 42 immediately above thediaphragm 43. When the pressure in such parts is sufiicient to overcomethe tension of the spring 4E7, the diaphragm will be forced downwardlyand cause the opening through the port 45 to be more or less closed,

thereby shutting off to some extent, or entirely, the gas from theburner 29 or by decreasing the opening aforesaid, correspondinglyreducing the. size of the flame produced by the burner. The tension ofthe spring 47 may be varied by'means of the adjusting screw 48 so thatthe movement of the die. pln'agm 43 will require a higher or lowertemperature, as the case may be, within the vessel 14, I to operativelyafiect the phragm43 in a manner heretofore described. If the tension ofspring 47 is increased by means of the screw 48, the operation of thediaphragm will be unafiected until the Water has been substantiallyexhausted from the vessel 14 and a dry heat is caused to pass outthrough the openings 67 and down the due 66, thereby affecting the fluidcontained within the chamber or receptacle 6st to a greater extent thanwhen steam only passes through said flue. By this means the contents ofthe vessel 14 is protected against burning, as it is practicallyimpossible to produce an intense hat'from the burner 29 after the waterhas been exhausted from the vessel. Now if the top 17 be raised for anypurpose, the heat contained in the fine 66, the lower iid of. which isopen, will be forced out by a reverse draft of relatively cold airentering the bottom of the flue and passing out through the openings 67,thereby cooling the receptacle 6% a nd permitting gas to enter theburner to increase the'size of the flame and consequentlya correspondingincrease of heat. When the top 17 is raised the vessel 14 may be readilyremoved from the jaCketlO as may also the flue Wall 65 attached to thevessel 14 and encompass.

ing, the receptacle 64, without disturbing any of the automaticallyregulating gas devices. In Fig. 1 I show three vessels 70, 71, and 72,that maybe placed in the vessel 14 for containing separate'articles offood, and it will'be? observed that these vessels extend above the upperedge of they jacket 10 so that they may be readily removed when the 7top is raised. I

A stand 73- is !provided with a. rim 74: which surrounds t e device. andprevents its accidental displacement. The stand is also provided with.three inwardlyextending arms '75, near its bottom, to provide a. rest13o oam-1a for a receptacle 56. In said fi re, a hose 7 7 is shownconnectedto the gas urner.

78 indicates an illuminated opening, orclinarily closed by a plate ofmica, or the 1 like, secured to a sliding door, which latter is operableby a'knob 79, for the purpose of permitting inspection of the interiorof the casing 10, or for lighting the burner 60.. The flame may be seenthrough the substantially t'ansparen't panel, covering the opening inthe door, without the necessity of; openin the door.

lvhil e I have herein shown and described a single embodiment of myinvention for? the purpose of clean disclosure, .it is evi-j dent thatchanges may be made therein 1 without departing from the spirit andscope E of the appended claims.

What I claim is:

1. A "device of the character described comprising a cooking vessel anda substantially tight fittin top therefor; controllable means for fuelor heating the contents of said vessel; a responsive means for controlling said fuel controllable means; a jacket opened at one end into saidvessel and at its other end to the atmosphere, said jacket surroundingsaid heat responsive means whereby heated vapor escaping from saidvessel must pass through said jacket. around said i l l l i I l lresponsive means, when the vessel is closed,

and a cooling blast of air will pass through i said jacket when saidvessel is open.

2. A device of the character described I comprising a cooking vessel anda substan- I tially tight fitting top therefor; a controllable means forfuel for heating the contents of stllt'l vess l; a heat responsive meansfor controlling said fuel controllable "means; a vertically disposedjacket secured to said vessel. open at its upper end into said vesseland at its bottom end to the atmosphere, said jacket surrounding saidheat responsive means. whereby heated vapor escaping from Isaid vesselmust pass down through said jacket around said responsive means, whenthe vessel is closed, and a cooling draftof air will pass upwardlythrough said jacket when said vessel is open.

3. A device of the character described comprising a cooking vessel and asubstantially tight fitting top therefor; a jacket surli-mnicliiig saidvessel providing thereby a combustion chamber; a fuel burner supportedl) and in the lower part of said jacket for heating the contents of saidvessel; a smaller jacket attached to the side wall of said cookingvessel. said jacket open at its upper end into said vessel and at itslower end into said combustion chamber; a fuel controlling meanssupported by said jacket and burner, and a heat responsive means forcontrolling said burner inclosed in said smaller jacket.

In testimon whereof I hereunto set my hand in the presence of twowitnesses.
